It isn't always a good idea for famous celebs to make cameos on kid's TV shows or movies. People make mistakes and sometimes those mistakes overshadow any cameo that might have seemed like a good idea at first. When celebs first sign onto be part of a kid's TV show or movie, they don't always know what they are getting themselves into.

Some actors, actresses, musicians, models, and reality TV stars have chosen to appear in kids' shows as themselves while others have taken on new and fictitious character personas. Either way, these are some of the most awkward appearances from celebs to date that might make parents reconsider if the show is good enough for their child to watch or not.

10 Gordon Ramsay In Phineas And Ferb

Gordon Ramsay In Phineas And Ferb

Gordon Ramsay appeared as himself in animated form on an episode of Phineas And Ferb. The cameo wouldn't be considered as awkward if his character didn't have to fire someone on the spot! The animated version of Ramsay fired one of his employees at random on the episode titled 'Thanks But No Thanks'.

9 The Backstreet Boys In Arthur

The Backstreet Boys In Arthur

The popular boy band from the 90s, The Backstreet Boys, appeared in an episode of Arthur as themselves. What makes this episode so awkward? The hilariously adorable character of Muffy (who has been used as a meme several times over the last several years) bounced around from being a fan of Nick Carter to Howie. Then she changes things up again and starts fangirling over A.J. What about Brian and Kevin?!

8 Chris Kirkpatrick In Fairly Odd Parents

Chris Kirkpatrick In Fairly Odd Parents

Chris Kirkpatrick played an exaggerated and fictional version of himself with a different name on Fairly Odd Parents for an arc of episodes. The character he played was named Chip Skylark, a ditzy and airheaded singer that girls pine after. The reason this is awkward is that Chris Kirkpatrick is basically playing into the fact that who he is as a singer in real life (as part of NSYNC back in the day) comes off as ditzy and airheaded... just like Chip Skylark.

7 Katy Perry In Sesame Street

Katy Perry's episode of Sesame Street was considered inappropriate by parents all over due to the fact that she had quite a bit of cleavage showing. Katy Perry isn't one to promote modesty or clothing that hides one's body so what did everyone even expect?!

Katy Perry is such a beautiful and talented singer, songwriter, and performer. The producers of Sesame Street should have given her better direction and guidance on what to wear!

6 Larry David In Hannah Montana

Larry David made a cameo on Hannah Montana as himself. Guest stars on Hannah Montana usually do amazingly well! We're talking about Dolly Parton, Alison Brie, Brooke Shields, and more. Why did Larry David's cameo have to come out so awkwardly? Probably because he played the role of a very impatient and fidgety man who did not want to wait in line.

5 Joe Biden In Where In The World Is Carmen Sandiego?

Joe Biden In Where In The World Is Carmen Sandiego?

President-Elect Joe Biden once appeared as himself in the 1993 live-action version of Where In The World Is Carmen Sandiego? The movie was based on a video game that was created in the 80s. Back in 1993, Joe Biden was just the senator. It's is pretty crazy that he is soon going to be the president of the United States... and that he once appeared in such a silly video game-themed movie.

4 Larry King In Gravity Falls

Larry King appeared in Gravity Falls as an animated version of himself in an episode called "Headhunters" where he voiced a wax figure of himself. Larry King also appeared in another episode called "Weirdmageddon 3: Take Back The Falls."

The only thing that makes this celebrity cameo so awkward is that he plays a wax figure version of himself (not a human version of himself) with a bit of an attitude!

3 Alice Cooper In The Muppet Show

Alice Cooper's cameo in The Muppet Show is awkward because it is much more dark and eerie than it needs to be. She plays the role of someone claiming to work for the devil who can cut the Muppets a deal for a lifetime of riches and fame. How creepy is that?! The episode aired in November of 1978.

2 Macklemore In Sesame Street

Macklemore In Sesame Street

The reason people collectively find Mackelmore's cameo in Sesame Street so awkward is that he spent his time rapping about trash. He is a rapper and a very talented one at that! But it would have been cool to hear him rap about the anti-bullying movement, how to be a good & honest friend, or why it's important to stay in school. The trash rap was catchy but could have been totally different, based on a different subject.

1 OJ Simpson In Disney’s Adventures In Wonderland

OJ Simpson In Disney’s Adventures In Wonderland

Looking back retrospectively, people now find OJ Simpson's cameo in Disney’s Adventures In Wonderland a bit awkward and cringe-worthy, knowing what we know now. His scandalous court case revolving around the murders of Nicole Brown and Ron Goldman completely overshadow any reasoning for him to be included on a kid's TV show or movie.
